5 Cla-ums.` (01.1559522y t Heretofore in saddle covers for this purpose the construction of the cover comprises a fabric of flax or similar coarse yarns which is vulcanized to rubber or a rubber compound. The purpose of this construction is to give the saddle cover both perfect tensile strength and also great elastic- `ity, as the tensile strength against tearing deconstituting the same a special form. For in-I stance, the fabric has been made so `loose in Weaving that the yarns were able to be displaced with respect to one another. Moreover, in order still further to increase the elasticity, constructional forms have been produced in. which the warp and weft yarns do not lie in the longitudinal and transverse axes of thesaddle cover, the fabric insert being in fact embedded diagonally of the rubber foundation. I

Due to the latter constructional form there is apparently a greater elongation when the saddle is under load, as the yarns are not stretched longitudinally so that the rubber foundation is not hindered in its expansion. In this case the fabric is pulled apart diagonally so that the warp and weft yarn carry out a movement in the manner of shear legs.

In all these constructional forms the elongation of the fabric has put a limit to the elongation of the saddle cover although it was intended to obtain `a particularly supple cover by means of the rubber foundation.

In my present invention I provide reinforcements of fabric or equivalent material in a saddle cover of rubber or similar resilient material in such a manner that reinforcements from opposite sides or ends are not directly connected to each `other but are intermeshed or otherwise arranged and connected through the rubber ofthe cover. The reinforcements are preferably embedded and vulcanized in the rubber material. They are connected by the rubber in a zone in the centreof the cover which is free from fabof this central zcmebetweenk the edges `of the fab-Y ric inserts, one or more rubber beadings which produce a reinforcement of the cover at thisI point, where it is Anot reinforced by the canvas insert. 'v

The invention is illustrated by way of example in the accompanying drawing, in which Fig. 1 is an inverted plan View of an embodiment of the invention, seen from beloW.`

Fig. 2 is a section on` the line C-D of Figure l. Fig. 3 a section on the line A-B of Figure l. Figs. 4, 5y and 6 are inverted plan views of modined forms of the invention.

In Figure l a designates a fabric strip which is vulcanized into the rear edge of the cover, and b is a further fabric strip vulcanized into the front edge of the cover;` c are rubber headings for reinforcing the rubber portion in order to elimric. Further there are arranged transversely inate the risk of tearing the centre portion of the cover, where no fabric strip has been inserted. Thisrubber beading c extends from the front to the rear fabric insert and is preferably approximately in the shape of a cigar, so that the thickest part lies approximately in the centre of the saddle cover, where the risk of tearing the cover is greatest.

Now, when the saddle is placed under load, there is nothing to hinder its elongation at the portion where there is no fabric insert as there.

is no fabric there to oppose this elongation. But due to the insertion of the fabric a tearing of the rubber transversely of the direction of elongation is avoided.

Figures 4 to 6 illustrate further constructional forms. In these, the fabric strips a, b are provided with' extensions d which may mesh with one another in the manner of a comb, so that the tearing line, if the rubber should tear transversely of the direction of elongation, Would have to be substantially longer than the straight transverse tearing line, and this almost entirely eliminates the danger of tearing. In this manner the saddle attains high tensile strength Without at the same time losing any of its requiste elasticity, as the fabric insert does not form one continuous whole from back to front of the cover Vbut is composed of a front and a back strip which in this special manner are connected only by the intervening rubber.

`As illustrated in Figures 4 to 6, several rubber headings may of course be used in the control zone ofthe saddle.

WhatI claim and desire to secure by LettersV c of rubber forlned to it the saddle, a fabric strip vulcanized into the narrow front part of said cover, a further separate strip cf fabric vulcanized into the wide rear part of said cover and inwardly directed tongues formed on the said 5 strips, said tongues intermesh'ing in spaced relationship with each other.
